Guillemin symmetrical half coupling, firefighter, without lock with male threaded sleeve in copper alloys

Guillemin male symmetrical half coupling without lock in copper alloys (Reference: 101316)

Multitanks presents this high-quality professional coupling, specially designed to meet the strictest requirements of fire services and critical industries. Made from premium copper alloys, this Guillemin half coupling guarantees exceptional corrosion resistance and unmatched durability in the most demanding environments.

Professional applications and use cases

This Guillemin symmetrical half coupling finds its place in many sectors where reliability and connection speed are crucial. Fire fighting services adopt it for its perfect compatibility with standardised equipment and its intuitive handling, even under pressure.

In the industrial sector, it excels for fluid transfers in the petroleum, chemical, petrochemical and pharmaceutical industries. Its lockless design allows for fast and safe maintenance operations. The food and beverage industry appreciates its compatibility with hygiene standards, while agriculture and irrigation benefit from its robustness for intensive irrigation systems.

Steel mills, construction and the transport of bulk liquids or powders are also preferred areas of application, thanks to its ability to withstand significant mechanical stresses.

Technical specifications and material innovation

The copper alloy design gives this coupling remarkable mechanical and chemical properties. These carefully selected alloys offer excellent corrosion resistance, even in the presence of moisture, salts or aggressive chemical agents.

The BSP thread (British Standard Pipe), also known as "gas thread", complies with international standards for maximum compatibility with existing equipment. This tapered thread ensures progressive sealing when tightened, without requiring an additional seal in most applications.

The symmetrical design allows bidirectional use, thus optimising the versatility of the coupling. The absence of a lock simplifies fast connection/disconnection operations, particularly appreciated in emergency situations or during frequent maintenance.

The male threaded sleeve is precision machined to guarantee a perfect assembly and optimal transmission of mechanical forces. The careful finish limits premature wear and facilitates cleaning.

Installation and optimised use

Installing this Guillemin half coupling requires a few precautions to ensure optimal performance. Check the cleanliness of the contact surfaces before assembly and ensure that the BSP thread matches the female element perfectly.

For tightening, apply progressive and uniform force. The BSP tapered thread should engage naturally without forcing. In the event of abnormal resistance, check the alignment and condition of the threads. A suitable wrench may be required for the final tightening, respecting the recommended torque.

In use, this coupling accepts high service pressures thanks to its robust design. It can be used indifferently for suction or discharge, adapting to the specific constraints of each installation.

Maintenance consists mainly of regular cleaning and checking the condition of the threads. Copper alloys resist common cleaning agents well, but avoid overly aggressive products that could damage the surface.

Expert advice and product synergies

To optimise the performance of your installation, pair this half coupling with hoses and accessories of comparable quality. Multitanks recommends the use of reinforced hoses for high-pressure applications and food-grade seals when the application requires it.

In irrigation systems, combine this coupling with our surface or submersible pumps to create a complete and reliable installation. For industrial applications, our Camlock fittings can effectively complement Guillemin connections according to specific needs.

Seasonal advice: during winter periods, completely drain the circuits to avoid damage caused by freezing. Copper alloys, although resistant, can suffer from extreme thermal stress.

Avoid the common mistake of over-tightening, which can damage the threads. The BSP thread is designed to seal progressively; moderate tightening is generally sufficient.

For professionals, consider acquiring multiple diameters to adapt your installations to the different flow rates required. Our complete range allows you to standardise your equipment while benefiting from Multitanks quality.
